In the winter of 1933, an 18-year-old named Patrick Leigh Fermor set out from the Hook of Holland to cross Europe on foot. His goal was Istanbul, which he bookishly insisted on calling Constantinople. He had little more in his rucksack than a volume of Horace and a few blank notebooks. He also had a bad reputation: The masters who expelled him from school — for a flirtation with a local girl — saw only “a dangerous mixture of sophistication and recklessness.” He spent the next year charming his way through a doomed prewar landscape of landed aristocrats, feudal peasants and benevolent monks, sleeping alternately in schlosses and hayricks. It was a journey that would become legendary, not so much for the extraordinary things he saw and recorded as for his prose — an utterly unique, hybrid vehicle that combines youthful exuberance with a dense, dauntingly erudite display of verbal artifice. Unlike most authors of travel literature (a rattlebag genre that doesn’t really do him justice) Leigh Fermor does not confine his role to that of camera obscura. He builds dense whorls of wordplay to echo the carvings in an old church door; he slips into baroque historical fantasias, scattering a shrapnel of words like “gabions,” “hydromel,” “eyot” and “swingle­trees” at the unsuspecting reader. In between salvos, there are moments of ferocious humor and quiet, lyrical beauty.

In part, this richness is a measure of the extraordinary gap between the experience and its narration. Leigh Fermor did not begin writing the first book about his journey, “A Time of Gifts,” until the 1970s. In the intervening decades, he had written several other books, becoming a fiercely learned autodidact and adventurer. His exploits during and after World War II — when he helped to kidnap the Nazi commandant in Crete and deliver him to a waiting British submarine — are said to have helped inspire his friend Ian Fleming, the author of the James Bond novels. As a result, the travel narratives are a kind of palimpsest in which his younger and older selves exist in counterpoint. He initially considered naming the first book “Parallax,” to reflect this split perspective.

Few books have been as keenly or lengthily anticipated as the third and final volume of Leigh Fermor’s youthful travels. (A second installment, “Between the Woods and the Water,” was published in 1986.) It never appeared; burdened by writer’s block and frailty, Leigh Fermor was still working on it when he died in 2011 at age 96. But he did leave a manuscript. His biographer, Artemis Cooper, and the British travel writer Colin Thubron chose to tidy it up and publish it as “The Broken Road,” a reference to the abrupt narrative halt before the author reaches Istanbul.

“The Broken Road” narrates Leigh Fermor’s travels in Bulgaria, Romania and Greece, a more tribal and violent world than Northern Europe. It does not always have the gemlike polish of the first two volumes. But it is an unforgettable book, full of strange encounters with a prewar Balkan cast of counts, prostitutes, peasants, priests and castrati. The greatest pleasure of all, as usual, is Leigh Fermor’s own infectious, Rabelaisian hunger for knowledge of almost every kind. His memory seems eidetic; his eyes miss nothing. He seems to carry within himself a whole troupe of sharp-eyed geographers, art historians, ethnologists and multilingual poets. For anyone who has tried to document a journey, reading him is a humbling and thoroughly inspiring experience.

“The Broken Road” is also full of his signature verbal architecture: The Orthodox bishops “in copes as stiff and brilliant as beetles’ wings, and the higher clergy, coiffed with globular gold mitres the size of pumpkins and glistening with gems, leaned on croziers topped with twin coiling snakes.” Or the Virgilian evocation of a passing flock of storks in the Balkan mountains, which goes on for pages: “All at once we were under a high shifting roof of wings, a flotilla that was thickening into an armada, until our ears were full of the sound of rustling and rushing with a flutter now and then when a bird changed position in a slow wingbeat or two, and of the strange massed creaking, as of many delicate hinges, of a myriad slender joints. They benighted the air.”

In some respects this book is even more satisfying than its predecessors because it is less guarded; the narrator emerges as an angrier, more troubled and more persuasive character. One of my few quarrels with “A Time of Gifts” is the dogged high-mindedness of Leigh Fermor’s youthful self. Where is the lust? Where is the rage? This man is 18 years old, for God’s sake. He never gives way to the curse-spitting xenophobia that overcomes most travelers (certainly me) at some point in their journeys. He runs into plenty of jams, and meets plenty of pretty young girls; but there is something a little too noble about him, too much of the innocent abroad.

This time things are different, and the young man seems to break free of his older narrator. At one point, lying on the damp earthen floor of a Bulgarian peasant’s hut, he gives way to revulsion at the “noisily hibernating rustics swathed all over this stifling hellhole.” He is overcome by self-hatred and yearns for the comfort and status of his school-bound peers. Elsewhere, he meets a spirited Bulgarian girl named Nadejda and falls in love with her; their romance, though apparently unconsummated, reeks of the adolescent emotional frailty that seemed absent in the earlier books.

One of the most vivid passages in “The Broken Road” takes place in Bucharest, where young Paddy (as all his friends called him) checks into what he takes for a modest hotel, the Savoy-Ritz, giving his bags to a baffled patronne. He returns late that night and discovers that it is not a hotel but a brothel. The laughing madam ushers him into the kitchen, where four attractive young prostitutes are eating a late supper: “I was given a chair and a glass of wine, and the girls on either side cut off bits of chicken breast and offered them on their forks with friendly solicitude.” The women, charmed by his youth and innocence, feed and fuss over him for several days, telling him stories about their clients and themselves, though he remains discreetly silent about whether he got anything for free.

“The Broken Road” ends in midsentence, and the editors have chosen to follow it with excerpts from the diary Leigh Fermor wrote in early 1935, mostly at Mt. Athos in Greece. These are fascinating precisely because they are so ordinary: Suddenly we see how lucky we are that Leigh Fermor chose to wait four decades before starting. Young men have strong legs and eyes, but it is the older narrator, with his multilayered perspective, who knows how to turn memory into art.

History also played a role. “The Broken Road” is strewn with ominous, proleptic hints about the future that only we — and the older narrator — are privy to. In “A Time of Gifts,” the Nazis were a constant presence, crass and often ludicrous, waiting to inherit Europe. In this book, it is both the Soviet boot and the Balkan breakup that lurk throughout, as young Paddy listens to his Bulgarian and Romanian friends spew hatred of one another. But he also evokes a quiet, starlit world where countless eccentricities of folk art and culture bloomed in isolated villages and persisted for centuries, untouched by the glare of television and the Internet. Much of this is gone now. We can be grateful he was there to record it.
